Abstract (en)

[origin: WO2014081371A1] Mobile broadband traffic has been exploding in wireless networks (300) resulting in an increase of interferences and reduced operator control. Networks (300) are also becoming more heterogeneous putting additional demand in interference management. There is currently no support for signalling of neighbor cell interference gleaned from soft and softer handover powers. Thus, there are no algorithms that accounts for and/or estimates interference impact factors between neighboring cells based on neighbor cell interference estimates gleaned from soft and softer handover power.To address these and other issues, techniques to accurately predict/estimate neighbor cell interferences that accurately accounts for own cell powers,soft handovers, softer handovers, neighbor cell interferences, and remaining neighbor cell interferences are presented. The described techniques estimate coupling effects of scheduling decisions in one cell to surrounding cells. In this way, interferences in the network (300) can be managed. To allow sharing of impact factors between network nodes (500), signalling techniques are also presented.
